Visual environments contain many cues to properties of an observed scene. To integrate information provided by multiple cues in an efficient manner, observers must assess the degree to which each cue provides reliable versus unreliable information. Two hypotheses are reviewed regarding how observers estimate cue reliabilities, namely that the estimated reliability of a cue is related to the ambiguity of the cue, and that people use correlations among cues to estimate cue reliabilities. Cue reliabilities are shown to be important both for cue combination and for aspects of visual learning. 相似文献

The aim of this research was to use a pure measure of aggression to clarify whether rejection sensitive children exhibit higher levels of aggressive behavior than those who are not as rejection sensitive and to examine whether the components of rejection sensitivity (RS) vary according to the types of aggression. A total of 287 Australian primary school students aged between 9 and 12 completed self‐report measures of RS and aggression. As expected, RS and its components, angry and anxious expectations of rejection, were linked to generalized aggression (GA) in adolescents, with angry expectations being more strongly associated with GA and in particular, proactive aggression. As expected, RS predicted reactive aggression better than it did proactive aggression and a three‐way interaction was found whereby the relationship between the type of RS and aggression differed as a function of the type of aggression. The present study offers new evidence to support the theory that RS is predictive of aggressive behavior in children and clarifies some confusion about the attributional affect and processes behind this behavior. The findings both support and extend existing research in the areas of RS and aggression. Aggr. Behav. 39:3‐12, 2013. © 2012 Wiley Periodicals, Inc. 相似文献

The present work examined predicted relations among Life History strategies, Executive Functions, socially antagonistic attitudes, socially antagonistic behaviors, and general intelligence. Life History (LH) theory predicts that Executive Functions and socially antagonistic attitudes and behaviors underpin an interrelated and coherent set of behavioral strategies (LH strategies) designed to enhance reproductive success. Specifically, LH theory predicts a positive relation between Executive Functioning and LH strategies; a negative relation between socially antagonistic attitudes and behaviors and LH strategies; and that Executive Functions mediate relations among LH strategies and socially antagonistic attitudes and behaviors. Results from a Structural Equation Model (SEM), based on self-reported Life History strategies, Executive Functioning, socially antagonistic attitudes and behaviors, and general intelligence support these predictions. The structure of the model suggests that Executive Functions serve a mediating role in the relations between LH strategy and social deviance. 相似文献

This research investigated how teachers express links between ideas in speech, gestures, and other modalities in middle school mathematics instruction. We videotaped 18 lessons (3 from each of 6 teachers), and within each, we identified linking episodes—segments of discourse in which the teacher connected mathematical ideas. For each link, we identified the modalities teachers used to express linked ideas and coded whether the content was new or review. Teachers communicated most links multimodally, typically using speech and gestures. Teachers’ gestures included depictive gestures that simulated actions and perceptual states, and pointing gestures that grounded utterances in the physical environment. Compared to links about new material, teachers were less likely to express links about review material multimodally, especially when that material had been mentioned previously. Moreover, teachers gestured at a higher rate in links about new material. Gestures are an integral part of teachers’ communication during mathematics instruction. 相似文献

Abstract The State-Trait Personality Inventory and the Anger Expression Scale have been attracting increasing attention in research involving personality assessment, but no data regarding the test-retest reliability of these instruments have been published. The 14-day test-retest correlation coefficients for the subscales of these instruments reflect appropriately low stability for the state scales of the STPI and moderate stability for the STPI trait scales as well as the AX subscales. 相似文献

Latency in Freud's psycho-sexual model is questioned as a somewhat perilous notion, seldom experienced indeed as a latent period as regards sexual and other drives. This appears to be reflected in the literature. Instead, the author suggests following Hartung with regard to a latency mode rather than a latency stage: the latency mode refers to a mind-set into which it is desirable to enter when engaged in learning, at whatever age, and wherever the learning situation. The perils of latency are then also those factors that inhibit that mind-set, and therefore the capacity to learn; six major factors are then considered in relation to difficulties in learning, mainly drawing upon examples in the setting of further and higher education. 相似文献

Young Hispanic and Caucasian children viewed an animated educational television program in conditions that varied the level of interaction required. Girls and Caucasian children identified with the Hispanic female character more than boys and Hispanic children did. Children who actively responded to character prompts were more likely to understand the important program content than were those who simply observed it. Interaction was especially beneficial to Hispanic girls. The results suggest that programs designed to involve children in the content through participation or interaction provide unique opportunities for children to learn important educational media content, and that even very young children are sensitive to qualities of the symbolic role models who deliver those messages. 相似文献

In this article, we combine two analogue experiments in which we empirically examined three malingering methodological issues in individuals trained and instructed to simulate posttraumatic stress disorder (PTSD) on the Trauma Symptom Inventory (TSI; Briere, 1995). In Experiment 1, we examined TSI scale effects of the following manipulations using a 2 × 2 design with 330 college students: (a) inclusion or exclusion of cautionary instructions regarding believability of participants' simulation and (b) different financial incentive levels. In Experiment 2, we examined comorbid psychiatric diagnostic training with 180 college students who were either trained to simulate PTSD and comorbid major depressive disorder or trained to simulate only PTSD. Caution main effects were significant for all but two TSI Clinical Scales, incentive main effects and interactions were only significant for one Clinical scale each, and the comorbidity manipulation did not yield any scale differences. We discuss malingering research design implications regarding the use of cautionary instructions, financial incentive levels, and comorbid training. 相似文献

The test for cluster bias is a test of measurement invariance across clusters in 2-level data. This article examines the true positive rates (empirical power) and false positive rates of the test for cluster bias using the likelihood ratio test (LRT) and the Wald test with ordinal data. A simulation study indicates that the scaled version of the LRT that accounts for nonnormality of the data gives untrustworthy results, whereas the unscaled LRT and the Wald test have acceptable false positive rates and perform well in terms of empirical power rate if the amount of cluster bias is large. The test for cluster bias is illustrated with data from research on teacher-student relations. 相似文献
